+# Service Directory
+
+[Service Directory](https://cloud.google.com/service-directory/) is a platform
+for discovering, publishing, and connecting services. It offers customers a
+single place to register and discover their services in a consistent and
+reliable way, regardless of their environment. These sample Java applications
+demonstrate how to access the Service Directory API using the Google Java API
+Client Libraries.
+
+## Prerequisites
+
+### Enable the API
+
+You must enable the Service Directory API for your project in order to use these
+samples.
+
+### Set Environment Variables
+
+You must set your project ID in order to run the tests
+
+`$export GOOGLE_CLOUD_PROJECT=<your-project-id-here>`
+
+### Grant Permissions
+
+You must ensure that the
+[user account or service account](https://cloud.google.com/iam/docs/service-accounts#differences_between_a_service_account_and_a_user_account)
+you used to authorize your gcloud session has the proper permissions to edit KMS
+resources for your project. In the Cloud Console under IAM, add the `Service
+Directory Admin` role to the project whose service account you're using to test.
+
+More information can be found in the
+[Authentication docs](https://cloud.google.com/docs/authentication/production).
+
+## Quickstart
+
+Install [Maven](http://maven.apache.org/).
+
+Build your project with:
+
+    mvn clean compile assembly:single
+
+You can run all tests with:
+
+    mvn clean verify
